Porsche 944 Turbo

The Porsche 944 is a luxury sports car that was built by Porsche from 1982 to 1991. It used the 924 platform that remained in production until 1988. The 944 was intended to last into the 1990s, but major revisions planned for a 944 "S3" model were eventually combined into the 968 instead, which replaced the 944. The 944 was available in coupé or cabriolet body styles, with either naturally aspirated or turbocharged engines.

For the 1985 model year, Porsche introduced the 944 Turbo, known internally as the 951. This had a turbocharged and intercooled version of the standard car's engine that produced 215 HP in the US at 6000 rpm. In 1987, Car and Driver tested the 944 Turbo and achieved a 0-60 mph time of 5.9 seconds. The turbo was the first car using a ceramic port liner to retain exhaust gas temperature and new forged pistons and was also the first vehicle to produce identical power output with or without a catalytic converter. The Turbo also featured several other changes, such as improved aerodynamics, notably an integrated front bumper. This featured the widest turn signals (indicators) fitted to any production car, a strengthened gearbox with a different final drive ratio, standard external oil coolers for both the engine and transmission, standard 16 inch wheels (optional forged Fuchs wheels), and a slightly stiffer suspension (progressive springs) to handle the extra weight. The Turbo's front and rear brakes were borrowed from the Porsche 911, with Brembo 4-piston fixed calipers and 12-inch discs as ABS also came standard. Engine component revisions, more than thirty in all, were made to the 951 to compensate for increased internal loads and heat.
